The Yanagawa family became a father-son family with one father and one child two years ago before his mother. The father works hard for his daughter day and night, and when he sees his father, his daughter Mako grows up quickly without being misconducted and lives in harmony with her parents. However, Mako eventually began to feel more emotional towards her father than her father, and spent days masturbating and comforting herself as if to kill such feelings. One day when love and lust can't be suppressed, Mako takes a general action without thinking ahead! !!
